To all whom it may concern:

Be it known that I, ELMER BUBB, EL citizen of the United States, residlng at Ch1- cago, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in Transmission-Cone- Gearing Apparatus; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, ref erence being had to the accompanying draw:

various details of construction, combinations and arrangements of-parts which w1ll behereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

lVIy invention is illustrated in the accompanying drawings, in which:

Figure 1 is a top plan View of my cone transmission apparatus, parts being-shown in section. Fig. 2 is a side elevation, and Figs. 3, l and 5 are detail views of parts of the mechanism.

Reference now being had to the details of the drawings by letter, A designates a driving shaft journaled in suitable bearings A", and B designates a stepped cone wheel loosely journaled thereon.

C designates a hand wheel having an integral collar C thereon having circumferential threads C and which-are adapted to engage the interior threads D formed within the shellD which is fastened stationary to the plate D F designates a collar which is fixed to the shaft A, and G designates an angle lever pivotally mounted upon a pin G carried by the collar F, and II is a coiled spring hearing between the shaft A at one end of the lever Gr andtending, to hold the opposite end G within a recess B formed in the face of the cone wheel B.

Mounted. loosely upon'theshaft A and having a longitudinal movement thereon is a clutch pulley I, one end 1' of which is recessed, having a tapering wall adapted, as the member I is moved in one direction, to

contact with the angle lever G to tilt the same. Said clutch pulley has a contracted portion I engaged by the forked lever K which is pivotally mounted upon a pin K.

L designates aguide bar which is slotted for-the receptionof thelever K, and O, O designate buttons which are adapted to engage the lever K to'hold the same at its limit in one direction or the other.

A counter shaft N is .journaled in suitable bearings N and a second stepped cone Q is fixed to the shaft N, the steps of the two cones B and'Q, being arranged opposite each other, as shown in'Figfl of the drawings, in order to obtain a variation in the speedof the driven shaft N. 1

A shaft it is pivotally connected at R to a link R which is guided in its movements by the strap R engaging a recess in said block, said block also being recessed upon itsunder surface to engage over the top R of the standard It, and said shaft R has two fixed collars R and R thereon, spaced apart and adjacent to the loosely mounted gear wheel T which is used for transmitting motion from one cone gear to the other in one or the other of the series of stepped portions thereof accordingly as it may be desired to vary the speed to be transmitted to the driven shaft. A plate'S, having grooves S in the upper edge thereof and corresponding to each pair of stepped portions of the cones, is fixed in diagonal relation to the length of the shaft Band in one or the other of which grooves the shaft R is adapt ed to be held accordingly as it may be desired to throw the wheel Tintermediate one or another of the two oppositely disposed steps of the cones.

A bar S is pivotally mounted on a pin S at one end of the plate S and its other end is slotted as at S to receive the staple S affording means for locking the shaft in an adjusted position.

Inoperation, it beingunderstood that the shaft A'is driven from any suitable source of power and constantly in rotation, the

initial rotary movementis imparted to the cone B by turning the hand wheel C which will move the end of the cone frictionally in contact with the rotatingcollar F, thus causing the cone to rotate therewith and forming means for starting the rotary movement of the cone gearing gradually, after which the lever K maybe thrown away from the cone wheel B, causing the clutch member I to release the angle lever Gr to allow the end thereof G to engage the notch or recess B in the face of the cone gear, thus forming a positive means for causing the cone to rotate with the shaft, afterwhich the Wheel C may be rotated to throw the hub portion thereof out of engagement with the opposite end of'the cone gearing. In the event of it being desired to transmit the fastest rotary movement to the counter shaft N, the operator by taking hold of the handle end of the shaft B may move the same to I cause the gear wheel T to be interposed between the stepped portion of largest diameter of the cone B and the stepped part of least diameter upon the cone wheel Q. When the wheel T is thus adjusted, the free end of the shaft It would rest in the groove at the. extreme left end of the plate S and would be retained therein through the medium of nism started and stopped gradually without any jerking or jarring to the various parts of the apparatus. v

A double cone transmission gear mech anism comprising a driven and a driving shaft, a speed cone fixed to the driven shaft and a loosely mounted cone upon the driving shaft, a collar fixed to the driving shaft, a pivotal member rotating with the driving shaft, means for throwing the same into engagement with the loosely mounted cone thereon, a transmission shaft and gearing loosely mounted thereon, and means for moving the transmission shaft intermediate the speed cones.
